CHRISTIAN H. MARTIN, OF AKRON, OHIO.

ADJUSTABLE BENCH.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed September so, 1912. Serial No. 723,093.

To all whom it may concern:

Be it known that I, CHRISTIAN H. MAR- TIN, a citizen of the UnitedStates, residing in the city of Akron, county of Summit,

and State of Ohio, have invented certain new and useful Improvements inAdjustable Benches, of which the following is a specification.

My invention relates to benches which are peculiarly adapted to be usedin connection with player pianos, as the seat may be raised from a lowerhorizontal position to an inclined position at greater height from thefloor. The lower level is employed when the pianist is playing upon thekeys of the piano in the usual way, while the upper inclined position isparticularly adapted for use when the bench is occupied by a person. whois operating the piano by mechanical.

playing means. At such times the greater height from the floor andinclined position are useful in aiding the person playing the piano tooperate the pedals with the greatest facility and minimum fatigue. Ihave shown crossed-lever means for accomplishing this result in myapplication for United States Letters Patent Serial Number 648,237,patented Dec.24, 1912, Serial Number 1,048,190.

The present application also provides one or more compartments or deepdrawers for containing music rolls used in connection with themechanical device for playing, the piano, which are normally concealedwithin the body of the bench and which are automatically ejected fromthe interior of the bench when the adjustable seat is raised to theupper inclined position. 1

In the accompanying drawings which form a part of this specification,Figure 1 is a longitudinal sectional view of my im proved bench with theseat in theupper inclined position and the music roll compartmentsejected from the sides of the bench; Fig. 2 is a similar view showingthe seat in the lower horizontal position and the music rollcompartments retracted within the bench; Fig. 3 is a transversesectional view on line III-III of Fig. 1; Fig. 4 is a perspective viewof the levers used for operating the musicroll compartments, and Fig. 5is a perspective view of the lever mechanism for accomplishing theraising and lowering of the seat.

Referring to the drawings in detail, the numeral 1 designates a benchhaving the vertical posts 2, mounted between the upper ends of which isa movable seat 3. The

seat ismounted at each of its shorter sides upon identically similarlever mechanism, each comprising the crossed-levers 4, 5. The upper endof the double lever 4 is pivoted at 6 to a bracket 7 afiixed to theseat, while the upper end of the lever 5 carries a pin 8 received in ahorizontal slot 9 in a bracket 10, also secured to the seat. The lowerend of'the double lever 4 carries a pin 7 11 which is received in a slot12 in a bar 13' permanently secured in any suitable manner to a fixedportion of the bench. The double lever 4 and the lever 5 are pivotallyconnected at 14, and the slot 12 is provided with one or more rests 15,16 for the reception of the pin 11. The lever 5 is notched at 17 and thebar 13 is notched at 18 to receive the pivot pin 6, when the levers arecollapsed, and the bar 13 is further provided with the notch 19 for thereception of the pivot pin 14, when the levers are in collapsedposition. The lever 5 is pivoted to the bar 13 at 19 The proportions andoperation of the device to accomplish the tilting of the seat when it israised, without causing its lateral displacement, are fully set forth inmy application above referred to and their description need not berepeated here. In addition to these two sets of levers I have shown mydevice provided with a third set of evening levers 20 and 21 extendingalong one of the long edges of the seat. These levers are pivotallyconnected at 22. The lever 21 is pivotally secured at 23 to the bottomof the seat and at its other extremity carries a pin 24 entering a slot25 in a bracket aflixed to a stationary part of the bench. The lever 20is pivoted at 26 to a fixed part of the bench and carries at its otherextremity a pin 27 entering a slot 28 in a bracket 29 secured to theunder-side of the bench. The function of this set of levers is to causethe seat to rise evenly; that is, without tilting from side to side whenit is raised. Without these 1evers, unless upward force is applied atthe center of one of the long edges of the seat, one of the short edgeswill be forced higher than the opposite edge, causinga tendency for theseat to jam between the opposite away with this difiiculty.

In connectionwith the seat-raising and The use of the evening leverswith 40f sight into the bench.

lowering'devices, I have provided compartments normally received withinthe body of the bench that do not become evident un-' til the seat israised to the position for use with mechanically operated pianos. In myimproved device the operation of raising the seat causes thecompartments to be ejected from the sides of the bench automatically, sothat the operator of the piano may readily select the roll which hedesires to attach to the piano. When he is through playing, the'merelowering of the seat will cause the compartments to glide back out Theserolls are usually sold in long rectangular boxes labeledupon one end,and I have so proportioned the compartments that the boxes may normallystand upon end therein, with the result that thelabels will be visibletothe operator Whenever the seat is in its ele- I vated position.

In the drawings the numerals 30 and 31 designate the two compartmentsadapted to reciprocate upon the rollers 32. Each of the compartments hassecured to it an angle bar 33 sliding under a roller 34 pivotallysecured'to a yoke 35 which is attachedto any suitable fixed part of thebench. The bar 33 and its roller 34 cooperate with the rollers 32toproduce an easy sliding action of.

each compartmentinto and from the cavity in the side of the benchprovided for it. Means for automatically controlling the 'movement ofthe compartments include a bent lever 36 pivotally attached at 37 toangle irons 38 and 39 secured to some suitable fixed part of the bench.The curved extremity of each lever 36 is pivoted at 40 to a twisted link41 which has its other ex- 40 i at right angles to that of the pivot 40,to

"an angle iron 43 adapted to be secured at 44' tremity pivoted at '42,in a plane disposed tothe under-side of the seat. The extremity of thelonger arm of the bent lever 36 carries a spool roller 45, the flangesof which embrace a rod 46 secured to brackets 47 and 48, which are. inturn fastened to the inner end of a music roll compartment. The

flanges of the roller 45 are also adapted to press against the inner endof the music roll compartment when the seat is raised.

It will be seen that when the person desiring to use the bench in theelevated posi- I tion raises the seat, the twisted rods 41 will 'belifted, causingthe'lever 36 to fulcrum about its pivot 37 and draw thelonger arm of this lever from the position shown in Fig. 2 into theposition shown in Figs. 1 and 4. The flanges of the rollers 45 will bearagainst their'respective compartments,

forcing them outward from the bench into jthe position shown. inthejtwolast named lfigures. WVhen the seat is lowered into the .positionused for playing upon the piano manually, this operation will bereversed.

The levers 41 will then be forced vertically downward, causing thebarrel of the spool rollers 45 to engage with their respective bars 46and retract the two compartments into the interior of the bench. It willthus be seen that the mere raising or lowering of the seat without anundue expenditure of force will cause the music roll compartments to bebrought into the position which is desired with the correspondingposition of the seat. It will further be obvious that a singlecompartment maybe used if desired, and that this compartment maybecaused to be ejected from the rear of the bench, instead of from theside.

While I have illustrated and described only one specific modification ofmy invention, I realize that it is susceptible of wide variation withoutdeparting from'the scope thereof and I do not wish to be limited tomovable compartment adapted to be received 1 within said bench, a leverpivoted to a fixed part of the bench, a link connecting the lever withthe seat, and means for communicating motion from the lever to thecompartment. r

3. In a bench, an adjustable seat adapted to be locked in a pluralityofpositions, a movable compartment adapted to be received within saidbench, a lever pivoted to a fixed part of the bench,a link connectingone arm 1 of the lever with the seat, and means connecting the other armof the lever-with the compartment.

4. In a bench, an adjustableseat adaptedto be locked in a plurality ofpositions, a i
